Nanoparticles create biocompatible capsules

exciting new health and agricultural applications," Granick said. "Chemical reactions can be performed within individual isolated capsules, or on groups of capsules linked together like boxcars in a train."

The biocompatible containers could carry cargo such as enzymes, DNA, proteins and drug molecules throughout living organisms. They could also serve as surrogate factories where enzyme-catalyzed reactions are performed. By attaching biomolecules to the capsule's surface, novel colloidal-size sensors could be produced.

An additional use for stabilized lipid capsules is the study of drug behavior. "A drug contained in this nano environment is like a fish swimming inside a bowl," Granick said. "We can study the 'fish' in detail, and it won't swim away."
